In the past i've seen two of the books that I'm looking for. One was for Tennessee and the other was for Arkansas. They were obviously from the same publisher but my internet searches haven't produced anything. So, here goes. They were red and had a road map of whatever state on the back cover. That map was gridded off and in each grid there was a page number (or page numbers) that showed that "section" of the main map. Has anyone ever seen one of these? I'd like to buy one for three or four different states. Thanks for any help.
